One, the paper tray usually refers to the paper tray in a broad sense, that is, the paper tray of the dry pressing process. The English name of the paper tray: Molded Pulp Packaging, abbreviated as MPP, scientific name: Pulp molding, which uses pulp as raw material, uses a stainless steel filter mold under pressure (negative pressure or positive pressure) and other conditions to dehydrate the pulp and form fibers And the processing method to produce the desired product. Paper tray production mainly includes pulp preparation, forming, hot pressing, molds and other processes. Mold forming includes vacuum forming method and extrusion forming method. Since most of the pulp used in pulp molding uses waste paper as raw materials, it conforms to the environmental protection requirements and the development direction of green packaging.
2. What are the application areas of paper trays?
Its application areas include electronics, electrical appliances, communication equipment, computer accessories, glass, ceramics, lighting, handicrafts, cosmetics, wine, fruits, eggs, etc.
3. What are the characteristics of the paper tray?
Compared with foamed plastic (EPS) products, paper trays have the following characteristics:
1. The raw material of the paper tray is waste paper, which is easy to recycle and will not cause pollution to the environment. It will be beneficial to the export of the manufacturer's products; the raw material of EPS is a petroleum by-product, which is difficult to degrade and has a low recycling value, which causes serious damage to the environment. "White pollution".
2. Paper trays have a wide range of applications. With the advancement of paper mold technology, medium and small industrial products that use foam as lining packaging can basically be replaced by paper trays.
3. The paper trays can be stacked and stored, which reduces the storage space occupied by EPS products by 1/2 to 2/5, which can greatly reduce transportation and storage costs.
4. Anti-static: EPS friction is easy to generate static electricity, while the paper tray is not easy to generate static electricity, which plays a better role in protecting electronic products and home appliances, especially electronic components.
5. Anti-corrosion performance: Food (such as fruits, etc.) will release water when stored. It is packaged with plastic products, and its water cannot be volatilized, which can easily make food moldy and rot. Paper products have good air permeability and water can be volatilized. Out, so as to achieve the anti-corrosion effect.
6. Shockproof performance: The shockproof and shockproof performance of the paper tray is the same as that of EPS products.
4. What is the thickness of the paper tray and the weight it bears?
1. The thickness of the paper support product is roughly between 0.5mm - 5mm, and the thickness of the general product is mostly maintained at about 1.0-2.5mm;
2. The large static load of paper mold packaging products can reach 1500 kg. Lined packaging for products weighing less than 50 kg is a good choice;
The paper mold material mainly depends on the design of the stiffener and the buffer cavity formed by the product. The design of the stiffener plays a vital role in the elastic deformation of the paper mold packaging product, that is, the cushioning capacity. The basic basis for the design of the stiffener It is the shape and shockproof requirements of the product itself.
5. What are the main properties of paper tray packaging products?
1. Buffering performance 2. Waterproof and moisture-proof performance 3. Anti-static performance 4. Degradable, easy to recycle, 100% environmental protection 5. Oil-proof.
6. What materials are used for the mold making of the paper tray products? How much is the production cost?
The main materials of pulp product molds are aluminum alloy, copper alloy, steel alloy and resin. The production of paper molded products is completed by two sets of molds, namely forming mold and hot pressing mold. The manufacturing cost of each mold is from 6000 yuan to 20000 yuan. Not waiting.
Seven, the wet press paper support is relative to the above dry press paper support, the following are the characteristics:
1. Product appearance: high smoothness, the paper support is molded by the upper and lower molds, and the inside and outside can reach the same smoothness, not rough, and lint-free;
2. Product accuracy: due to the particularity of the equipment, the mold is processed by CNC, with small rounded corners up to R2, with high accuracy, which can fit every angle of the product, like a close-fitting clothing to protect the product;
3. Not easy to deform: The paper tray produced by the equipment's mold drying process only contains 1% of water, so it will not be deformed due to moisture weathering when stored in nature;
4. Raw materials: raw wood (paper) pulp, sugarcane pulp, newsprint, black cardboard, etc. are used as raw materials for production. There are pure white, milky white, gray, black and other colors for you to choose, all of which are environmentally friendly materials;
5. Scope of application: Our paper trays are suitable for some electronic products that are high, light and capable of increasing the added value of the product. The company currently supplies paper trays for mobile phones, MP3s, digital cameras, set-top boxes, repeaters and small medical devices.
